Two approaches to the theory of OCA are distinguished in this paper. The first attempts to define the OCA from the point of view of a single country, and the second examines the optimality of a currency area of a given size anf membership. The present paper after reviewing the drawbacks of the...

The unemployment rate in Greece rose from a mere 2.2% in the 1970s to 6.4% in the 1980s and 10% approximately in the mid-1990s. Currently, it gravitates around that level. In this paper we present the stylized facts of unemployment in Greece and examine the causes of its abrupt increse in the...

Measured against PPP, the drachma effective exchange rate was overvalued by a significant amount, implying that the devaluation on March 1998 was an adjustment of the exchange rate towards the long-run price differentials. The paper also analyses the links between fiscal policy, interest rates...

In this paper we address the implications of production risk for controlling fishing effort in a regulated fishery in a framework where fishers maximize expected utility of profit. We focus on controlling effort through season closures that limit the number of days the fishery is open to harvest...

Time-varying GARCH-M models are commonly employed in econometrics and financial economics. Yet the recursive nature of the conditional variance makes exact likelihood analysis of these models computationally infeasible. This paper outlines the issues and suggests to employ a Markov chain Monte...

In this paper we are concerned with the issue of the existence of locally uniform Edgeworth expansions for the distributions of parameterized random vectors. Our motivation resides on the fact that this could enable subsequent polynomial asymptotic expansions of moments. These could be useful...

We consider a robust control model for a spatially distributed commercial fishery under uncertainty, and in particular a tracking problem, i.e. the problem of robust stabilization of a chosen deterministic benchmark state in the presence of model uncertainty. The problem is expressed in the form...

The increasing scarcity of natural resources (in terms of quantity and quality) is one of the most pervasive allocation issues facing development planners throughout the world. The need for sustainable management of these valuable resources has become a critical policy concern. Econometrics is a...
